EVACUATING REFRIGERATION SYSTEMS WITHOUT TIME-CONSUMING MONITORING
Testo relies on automation. With the new testo 565i vacuum pump.
Testo launches a new innovative product, the testo 565i vacuum pump, which enables fully automatic evacuation of refrigeration systems and heat pumps. This automated system is designed to save customers a lot of time and offer them greater flexibility in their daily work.
Evacuations are an important part of the commissioning and maintenance of refrigeration systems and heat pumps. They ensure the efficient performance and longevity of a system by removing unwanted foreign gases and moisture. However, this process can take several hours, especially in the case of larger systems. A vacuum holding test is carried out after evacuation to draw conclusions about the system tightness. All in all, this is a time-consuming process.
For this reason, Testo is focusing on automation with its new vacuum pump. When the required vacuum target values are reached, the testo 565i stops evacuation automatically and then starts the vacuum holding test. After a one-off configuration, the evacuation process runs entirely on its own allowing the technician to start filling the system immediately in the next step and view all the data collected on system tightness.
